Flexible Aqueous Depilatory Article

Abstract

A depilatory article comprising a substrate and an aqueous depilatory composition disposed on said substrate, forming a coated region of the substrate, wherein said substrate has a rigidity in the range of from 5.00 g / cm to 0.08 g / cm, preferably from 3.00 g / cm to 0.08 g / cm, more preferably from 1.80 g / cm to 0.10 g / cm, even more preferably from 0.80 g / cm to 0.15 g / cm and even more preferably still from 0.60 g / cm to 0.25 g / cm and wherein the aqueous depilatory composition comprises water in an amount of greater than 40%, preferably from 50% to 98%, more preferably from 60% to 95% and even more preferably from 70% to 90%, by weight of the aqueous depilatory composition.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 305,246, filed 17 Feb. 2010.FIELD OF THE INVENTION[0002]The present invention relates to depilatory articles comprising a chemically active depilatory composition disposed on a substrate.BACKGROUND OF THE INVENTION[0003]Depilatory compositions used to remove unwanted hair by chemical activity are known. Such compositions may comprise reducing agents to degrade keratin in the hair and thus weaken the hair strands. These compositions may take the form of creams, lotions and the like which may be applied to the unwanted hair in a variety of ways, such as with a spatula. The spatula or another suitable implement is then used to scrape off the weakened hair strands and complete the depilation process. This can be a messy and awkward procedure for the user of the depilatory cream or lotion and provides no means of occluding the aqueous depilatory composition to prevent it...

AI Technical Summary

Benefits of technology

[0005]According to a first aspect of the invention, the Applicants have surprisingly found that a depilatory article comprising a substrate and an aqueous depilatory composition disposed on said substrate, forming a coated region of the substrate, wherein said substrate has a rigidity in the range of from 5.00 g / cm to 0.08 g / cm, preferably from 3.00 g / cm to 0.08 g / cm, more preferably from 1.80 g / cm to 0.10 g / cm, even more preferably from 0.80 g / cm to 0.15 g / cm and even more preferably still from 0.60 g / cm to 0.25 g / cm and wherein the aqueous depilatory composition comprises water in an amount of greater than 40%, preferably from 50% to 98%, more preferably from 60% to 95% and even more preferably from 70% to 90%, by weight of the aqueous depilatory composition meets the aforementioned need by providing a depilatory article comprising a high-water depilatory composition, exhibiting a desirable balance between ease of handling during application and conformability to the surface of the body.

Problems solved by technology

This can be a messy and awkward procedure for the user of the depilatory cream or lotion and provides no means of occluding the aqueous depilatory composition to prevent it from drying out.

While addressing some of the usage problems of creams and lotions by removing the need for an application implement, known substrate-based depilatory compositions do not address the problem of achieving an improved balance between ease of handling during application, and conformability to the surface of the body to which they are applied.

While this may reduce pain associated with hair removal by reducing the extent by which hairs are removed from the skin by physical means, it also provides less adhesive quality to conform substrate to the surface of the skin.

Applicants have found that excessively rigid articles lack the capability to be conformed to the area of the body upon which there is unwanted hair, resulting in poor contact between the depilatory composition and the unwanted hair and hence an unsatisfactory hair removal process while substrates lacking rigidity will collapse during handling and be difficult to accurately place on the unwanted hair.
